Mq 2 Gas Sensor Arduino

The mq 2 smoke sensor is sensitive to smoke and to the following flammable gases.

Mq 2 gas sensor arduino.

Here s the list taken from arduino cc website. The output is an analog signal and can be read with an analog input of the arduino. You can get this sensor for several. How to detect dangerous fumes and smoke.

The output can be an analog signal a0 that can be read with an analog input of the arduino or a digital output d0 that can be read with a digital input of the arduino. The signal output voltage from the gas sensor will increase decrease when the sensor detects concentration of gas. Pin wiring to arduino uno. The mq series of gas sensors use a small heater inside with an electro chemical sensor.

Mq gas sensor type has many derived type for every certain gas. Guide for mq 2 gas smoke sensor with arduino. The mq 2 gas sensor. They are sensitive for a range of gasses and are used indoors at room temperature.

Keeping this in mind in today s post i have worked on mq 2 gas sensor fc 22 powered and interfaced with arduino uno. The mq 2 sensor has 4 pins. Mq 2 gas sensor arduino. Sensitivity can be adjusted by varying the trimmer onboard.

Breath checker or early fire detection system mq2 gas sensor module is a great choice. The mq 2 gas sensor module is useful for gas leakage detecting in home and industry. Give your next arduino project a nose for gasses with the mq2 gas sensor module. Mq gas sensor type is the most popular gas sensor for hobbyist easy to get and of course very cheap.

The mq 2 smoke sensor is the one in the following figure. This module is provided with male header interface and can be easily interfaced with arduino mega using male to female type jumper wires. For detailed information for the mq 2 sensor refer to the datasheet. This smoke detector can be easily built onto a breadboard or a polka dot plate.

The mq 2 sensor is used to detect the levels of gas around the area so you can utilize this. This project uses the mq 2 sensor and an arduino to determine and detect different smoke intensities. Alcohol carbon monoxide hydrogen isobutene liquefied petroleum gas methane propane and smoke. Many a times disastrous accidents take place due to leakage of these cylinders in these situations we must administer proper care and safety.

The mq 2 sensor is a versatile gas sensor capable of detecting a wide range of gases including. The best detection time for the sensor is should be 24 hours. This is a robust gas sensor suitable for sensing lpg smoke alcohol propane hydrogen methane and carbon monoxide concentrations in the air if you are planning on creating an indoor air quality monitoring system.
